Patented May 24, 1932 UNITED STATES PATENT OFFICE JEWELL W. VANDERVEER, OF ERIE, PENNSYLVANIA, ASSIGNOR TO ERIE MALLEAIBLE IRON COMPANY, OF ERIE, PENNSYLVANIA, A' CORPORATION OF PENNSYLVANIA WHEEL STRUCTURE Application filed May 31, 1927. Serial No. 195,289.

The present invention is particularly designed with relation ,to the manner of mounting the rim on a wheel structure. The specific wheel structure to which the invention is di rected is one which is designed for what is known as dual wheels. Such wheels have been provided with a bearing surface at the inner edges of the spoke ends and with corresponding surfaces at the outer edges of the spoke ends, these surfaces carrying the inner and outer rims respectively. It is desirable to provide a rim which may be interchangeable with such a structure and where one rim is used will be centrally mounted over the wheel. While the specific embodiment involves this adaptability the invention has some broader aspects, the details and featuresof which will appear more fully from the specification and claims.

A preferred embodiment of the invention is illustrated in the accompanying drawings as follows Fig. 1 shows a side elevation of a wheel.

Fig. 2 a section on the line 2-2 in Fig. 1.

Fig. 3 an enlarged section of a portion. of the wheel rim on the line 22 in Fig. 1.

Fig. 5 a section indicating the adaptability of the structure for a dual mounting.

1 marks the wheel center whichis secured to the usual hub 10., and 2 the spokes radiating from the wheel center. The outer ends of the spokes are each provided with a beveled surface 3 at the outer edge of the end of the spoke and a beveled surface 4 at the inner edge of the end of the spoke. These double bevels are particularly useful in the specific embodiment of my invention in that it adapts the structure for a dual rim mounting. An inner rim 5 is provided with a gutter 6 with a beveled under surface 7 which is adapted to engage the bevel 4. A positioning ring 8 engages the outer shoulder of the gutter 6 and is crowded by a shoulder 9 of a gutter 11 of the outer rim. An under surface 12 of the gutter 11 is engaged by the wedge .end of a clamping plate 13 which is wedged between the surface 12 and the surface 3.

In the present structure the rim 14 has an 50 inner tire ring 15 and an outer ring 16. The

outer ring 16 engages a locking ring 17, one

with a double taper, the inner taper corre:

sponding to thetapered surface 3 and the outer taper corresponding to the bevel 0r taper 19.

A clamping plate 21 engages the outer shoulder of the gutter 18. The plate is provided with a fulcrum lip 22 at'its inner edge and is secured to the face of the wheel spoke by a clamping bolt 23.

With this structure it will be observed that rim is centrally carried over the wheel and is carried by the outer engaging surface on the end of the spoke. Thus this demountable rim is interchangeable with a wheel structure adapted to carry the dual rim.

The ring 20 is split forming the ends 24. A plate 25 is secured to the underside of the rim and fills the space between the ends24= thus locking the rim with thebeveled ring 20. This is preferably arranged at the position of the valve stem 26 and between adjacent spokes. Shoulders 27 are formed in the rim preferably by striking out a small portion of the ring and these shoulders engage front and back circumferential faces of adj acent spokes, preferably the front face of the spoke in front of the valve stem space and the rear face of the spoke to the rear of the valve stem space. Thus the spokes are locked with the driving ring and in consequence with the rim.
